Mind-boggling software pops 3D objects out of your old photos

Quote

3-Sweep is a proposed piece of software that takes a 2D photo and pops out objects into full 3D models. While the technology seems highly complex, using it yourself looks relatively simple. Just trace around the object you want to 3D-ify and out it snaps.
Those objects can also then be manipulated and moved around the picture, which means we're pretty much looking at Photoshop on steroids.
